基于跟踪站模式下的GPS技术应用

随着GPS卫星轨道精度的提高、数据处理模型和方法的完善、软件的可视化、仪器性能的改善与性价比的提高,GPS技术在我国得到了广泛应用与发展。在构建空间数据基础框架之际,全国各地正在建立或改造GPS网。针对经典建网方法,介绍了基于跟踪站模式下的GPS技术,并以实例对数据处理方案、观测时间的选取进行了分析和比较。

The application of GPS technology that based on the tracking station

With the improvemet of GPS satellite orbit positioning accuracy,the perfect of the data processing model and methods,and the software and instrument functioning, GPS technique has made extensive application and development in China. Now, China planed to set up Spatial Data Infrastructure, many regions has established or reformed the GPS nets. GPS technology based on tracking station model is introduced for classical method of set up the GPS net. An example is given out on analysis and compare the different projects of data procesing and observation time.
